The bangladeshi word for micropenis, the condition of having an unusually small penis of at least 2.5 standard deviations smaller than the mean human penis size, or smaller than about 7cm (2 inches) for an adult when compared to an average erection of 12.5cm (5 inches). It occurs in .6% of males worldwide but in 4% of bangladeshi males.
In some areas in bangladesh it is thought that if a male in the family has this condition then the close females relatives will have good fortune as the man with the micropenis (or shuvo) has taken a large proportion of bad luck in the family.
